Duplicating Your Housekeys, From a Distance 287

Roland Piquepaille writes "Some clever computer scientists at UC San Diego (UCSD) have developed a software that can perform key duplication with just a picture of the key — taken from up to 200 feet. One of the researchers said 'we built our key duplication software system to show people that their keys are not inherently secret.' He added that on sites like Flickr, you can find many photos of people's keys that can be used to easily make duplicates. Apparently, some people are blurring 'numbers on their credit cards and driver's licenses before putting those photos on-line,' but not their keys. This software project is quite interesting, but don't be too afraid. I don't think that many of you put a photo of their keys online — with their addresses." I wonder when I'll be able to order more ordinary duplicate keys by emailing in a couple of photos.

Why Your Clock Radio Is All Abuzz About iPhones 397

blackbearnh wrote in with a story that's not really about the iPhone, but if your office speakerphones beep like mine does, read on: "If you own an iPhone, you may have noticed that it has a distinct and very annoying effect on clock radios, computer speakers, car radios, and just about anything else with a speaker. The folks at O'Reilly Media aren't immune, so they set out to discover just what is it about iPhones that makes them such bad RF citizens. The iPhones aren't the only bad apples in the cell phone basket and there's not much you can do about the problem. We're really in an interesting time in that there has never been so many high-powered personal transmitters just wandering loose in the world."

100x Denser Chips Possible With Plasmonic Nanolithography 117

Roland Piquepaille writes "According to the semiconductor industry, maskless nanolithography is a flexible nanofabrication technique which suffers from low throughput. But now, engineers at the University of California at Berkeley have developed a new approach that involves 'flying' an array of plasmonic lenses just 20 nanometers above a rotating surface, it is possible to increase throughput by several orders of magnitude. The 'flying head' they've created looks like the stylus on the arm of an old-fashioned LP turntable. With this technique, the researchers were able to create line patterns only 80 nanometers wide at speeds up to 12 meters per second. The lead researcher said that by using 'this plasmonic nanolithography, we will be able to make current microprocessors more than 10 times smaller, but far more powerful' and that 'it could lead to ultra-high density disks that can hold 10 to 100 times more data than today's disks.'"

Blogger.com Banned In Turkey 262

petermp writes "A Turkish court has blocked access to the popular blog hosting service Blogger (Blogger.com and Blogspot.com, owned by Google), since Friday, October 24th, 2008. According to BasBasBas.com, a Dutch blogger based in Istanbul, who alerted readers about the issue: 'It is suspected that the reason for this has something to do with Adnan Oktar, by some considered the leading Muslim advocate for creationism, who has in the past managed to get Wordpress, Google Groups, as well as Richard Dawkins' website [banned].'"

Cobol Job Market Heating Up 288

snydeq writes "Developers seeking job security in the years ahead could find an unlikely edge in Cobol. According to an InfoWorld report, demand for Cobol skills is surging, with salaries on the rise. More importantly, the short supply of offshore Cobol programmers and the fact that mainframes aren't going away anytime soon are spurring longevity for big-iron skills, with many companies looking to hire in-house Cobol pros to bridge mainframe Cobol apps to the rest of the enterprise. The report provides further evidence that Cobol may indeed be primed for a comeback, with new kinds of Cobol integration jobs emerging to prove old-guard skills are critical to some of the hottest areas of software development today."

Scientists Erase Specific Memories In Mice 320

Ostracus writes "It sounds like science fiction, but scientists say it might one day be possible to erase undesirable memories from the brain, selectively and safely. After exposing mice to emotionally powerful stimuli, such as a mild shock to their paws, the scientists then observed how well or poorly the animals subsequently recalled the particular trauma as their brain's expression of CaMKII was manipulated up and down. When the brain was made to overproduce CaMKII at the exact moment the mouse was prodded to retrieve the traumatic memory, the memory wasn't just blocked, it appeared to be fully erased."

Spore Expansion Announced, Another Coming In 2009 105

EA announced this week what many suspected for a while, now: Spore expansions are on their way. The first, due out in November, will be an addition to the creature creator, offering more parts for players to use. The next, due in Spring 2009, will provide new gameplay: "The expansion will give space-faring species the ability to beam down from their ships to explore other worlds and complete missions. And along with this, the expansion will include an Adventure creator, in which players can build — and then share — their own customized missions."

Report Indicates Widespread H-1B Visa Fraud 397

Vrst1013 notes a Business Week account of a government report examining fraud in the H-1B program. The US Citizenship and Immigration Services just released a report to members of the Senate Judiciary Committee examining issues with fraud and technical violations within this program. Based on a sample size of 246 H-1B petitions, 13.4 percent showed fraud and 7.3 percent showed technical violations, for an overall violation rate of 20.7 percent. There was slso evidence of payment below the prevailing wage, offers of non-existent jobs, and fraudulent documentation. "'The report makes it clear that the H-1B program is rife with abuse and misuse,' says Ron Hira, [a professor] at the Rochester Institute of Technology ... However, both Presidential candidates, Senator Barack Obama and Senator John McCain, have said they support expanding the program."

CNET UK Credits Claim That Apple Will Release Networked TVs 110

r2k writes "While the Apple rumours posted yesterday highlight some of the most commonly talked-about opinions, a writer for CNet UK sat down with Mahalo's Jason Calacanis, who told CNet he knew for a fact that Apple is developing fully networked LCD TV sets. As the writer points out, Apple dropped 'Computer' from its company name for a very good reason."

EU Wants Removable Batteries In iPhones 320

MojoKid writes "Current regulation, introduced with the Restriction of Hazardous Substances Directive (RoHS) in July of 2006, primarily sought to prevent the unnecessary use of toxic metals in batteries as well as making it easier to recycle and dispose of used batteries. The updated 'New Batteries Directive,' as discussed in New Electronics by Gary Nevision, would go much further. Article 11 of the directive, as currently written, would require that devices must be made in such a way as to allow batteries, either for replacement or at end of life for disposal to be 'readily removed.' Of course, Apple's iPhones and iPods wouldn't meet this requirement, as it stands. It's obvious that an iPhone battery replacement program could be considered a cash cow for Apple as well."

Netbook Return Rates Much Higher For Linux Than Windows 663

ivoras writes "An interview with MSI's director of US Sales, Andy Tung, contains this interesting snippet: "We have done a lot of studies on the return rates and haven't really talked about it much until now. Our internal research has shown that the return of netbooks is higher than regular notebooks, but the main cause of that is Linux. People would love to pay $299 or $399 but they don't know what they get until they open the box. They start playing around with Linux and start realizing that it's not what they are used to. They don't want to spend time to learn it so they bring it back to the store. The return rate is at least four times higher for Linux netbooks than Windows XP netbooks.'"

How Do I Talk To 4th Graders About IT? 531

Tsunayoshi writes "My son volunteered me to give a presentation on what I do for a living for career day at his elementary school. I need to come up with a roughly 20-minute presentation to be given to 4-5 different classrooms. I am a systems administrator, primarily Unix/Linux and enterprise NAS/SAN storage, working for an aerospace company. I was thinking something along the lines of explaining how some everyday things they experience (websites, telephone systems, etc.) all depend on servers, and those servers are maintained by systems administrators. I was also going to talk about what I do specifically, which is maintain the computer systems that allow the really smart rocket scientists to get things into space. Am I on the right track? Can anyone suggest some good (and cheap/easy to make) visual aids?"

Researchers Re-Examine Second Law of Thermodynamics 125

Many readers have written to tell us that researchers are examining the possibility of using Brownian ratchets to help combat the problem of heat dissipation in miniaturized electronics. "Currently, devices are engineered to operate near thermal equilibrium, in accordance with the Second Law of Thermodynamics which states that heat tends to transfer from a hotter unit to a cooler one. However, using the concept of Brownian ratchets, which are systems that convert non-equilibrium energy to do useful work, the researchers hope to allow computers to operate at low power levels, and harness power dissipated by other functions. 'The main quest we have is to see if by departing from near-equilibrium operation, we can perform computation more efficiently,' Ghosh told iTnews. 'We aren't breaking the Second Law — that's not what we are claiming,' he said. 'We are simply re-examining its implications, as much of the established understanding of power dissipation is based on near-equilibrium operation.'"
